2. Lots of big cities and harbors are next to the ocean and can harness the power of the waves for their use. This is because the production of power from the waves is in places where there are the least impacts on the environment. Also, not to mention that this energy resource is diminishing. Equipment that is exposed to rugged oceanic conditions 24/7 can lead to damage to wave equipment and to corrosion from salty seawater, requiring maintenance. In today’s energy-powered world, a source of clean energy is hard to come by. The energy in waves comes from the movement of the ocean and the changing heights and speed of the swells. The amount of power that can be produced from the waves is absolutely enormous. In a transverse wave, a medium’s movement – in our case, the medium is water – is perpendicular to the wave. It is not as clean as it seems. For this reason, tapping of wave energy can only occur in sites that have strong waves coming towards the shores. Being a nature lover, I feel it is my responsibility to show the real environmental problems that we are facing in this world to the public. It would also become the most sought after source of sustainable energy. Advantages of Wave Energy Disadvantages of Wave Energy 1. Wave energy is an irregular and oscillating low-frequency energy source that can be converted to a 60-Hertz frequency and can then be added to the electric utility grid. List of the Disadvantages of Wave Energy and Power 1. Above all, the wave energy is efficient. Many of our nations have a coastal region. The biggest advantage of wave power as against most of the other alternative energy sources is that it is easily predictable and can be used to calculate the amount that it can produce. A final benefit is that there are a variety of ways to gather it. But, wave energy is one of the clean forms of energy generated today. We discover that power can drop during a rough storm in the sea. This is because the probability of winds blowing over the ocean’s surface is high. Did you know that there are different forms of waves? Notify me of follow-up comments by email. As the winds blow over the ocean surface, they form waves. Also, unlike fossil fuels, creating power from waves creates no harmful byproducts such as gas, waste, and pollution. Thus it may leave huge holes in the ground and eventually, the land becomes barren. Now we have an idea as to why wave energy is beneficial to us. Although it is a clean energy source for the land environment, it poses a threat to the water environment. These are two different forms of energy. Referring back to fossil fuels energy generation, we discover that this energy is toxic to the environment. This form of energy has great future potentials. There are, however, many disadvantages to this energy source as well. After that, deduce its benefits and limitations to us. This provides a market for wave energy plants – a reason for its production. So what type of waves do these winds form? They look like large machines working in the middle of the ocean and destroy the beauty of the ocean. They must withstand rough weather. For this reason, we can enjoy electrical power without facing relocation issues. For this reason, the need for green energy will increase. There are also some of disadvantages of wave energy: Firstly, only power plants and towns near the ocean will benefit directly from it. Fossil fuels, on the other hand, have huge land impacts. Cons about tidal wave energy. 1) Environmental Effects. Know more about it here. The energy that comes from the waves in the ocean sounds like a boundless, harmless supply. So, landlocked countries or cities are unable to benefit from this source of renewable energy. It is so huge that just along the shore, the power density is approximately 30kW to 40kW per meter of a wave. This becomes interesting for us to determine which type of wave can generate wave energy. Wave energy is strong winds which act in the oceans. This study helps us to picture how wave energy is of use to us and future generations. There is maintenance to be taken care of. But wait, there’s— more to it than just a source of clean energy. Only power plants and towns near the ocean will benefit directly from it. Another benefit of using this energy is its nearness to places that can use it. Wave energy is a source of power that comes from the endless march of the waves as they roll into the shore then back out again. For example, waves reaching the shore can be used like a piston to push air up and down a large pipe. For this reason, the extraction of fuels is usually from underground. See Related: Pros and Cons of Nuclear Energy. The machines can pose a risk to the marine animals. Oceanic storms such as hurricanes are particularly damaging t… In this article, we can grasp the meaning of wave energy. As we mentioned this a couple of times before wave energy is a renewable source of energy, which means that we will never run out of it. So, it becomes inconsistent sometimes and unpredictable. It is operating optimal level of efficiency regardless of what the wave’s directions are. Because wave energy is still in the developmental stage, it is very costly to build wave devices. Individuals or towns in proximity to oceans and seas will enjoy the fruits of wave energy. From various studies and calculations, it is interesting to know that wave energy is stronger near the coast than in the ocean. The wave energy platforms installed in the water may obscure the natural and beautiful view of the ocean. If you want to go deep into the topic then The Author Michael E. McCormick ( is the Corbin A. McNeill Professor of Naval Engineering at the U.S. The first benefit of offshore wave power is that there is a larger energy potential in wave’s energy. The need for green energy in most of our nations may also turn to the exploitation of wave energy. Learn how your comment data is processed. As discussed earlier, we learned that water covers about 70 percent of the earth. Wave energy has plenty of potential thanks to the powerful movement of water around our planet. Unlike fossil fuels, which cause massive damage to land as they can leave large holes while extracting energy from them, wave power does not cause any damage to the earth. Many worked examples throughout the book will be particularly useful to readers with a limited mathematical background. Not only will it help to curb air pollution, but it can also provide green jobs to millions of people. It is also a clean form of energy since it does not need the burning of fossil fuels for generation. (And Ways to Reuse Old Lighters), 10 Different Alternative Sources of Energy, Can You Recycle a Mattress? This advantage is considered very useful in the generation of electricity. In this article, we discuss the advantages and disadvantages of wave energy which is as important as understanding how it works. As the technology improves and the demand for renewable energy technologies increases, the costs of investment and construction of wave energy technology are expected to decrease. Not only is that, despite the costs, the ocean is also a source of absolutely clean and renewable sources of energy. It is then, not a clean energy source for us all. Disadvantages of wave energy. Because of its source, wave energy is not a viable power source for everyone. Waves generated by the wind are used to convert into energy. But for the better of the environment, it is essential that we try taking this step. Those interested in research and development will benefit from the extensive bibliography. The biggest disadvantage to getting your energy from the waves is location. As the winds blow over the ocean surface, they form waves. The chances of the winds acting on the oceans are high. WHAT IS IT? Dependence on foreign companies for fossil fuels can be reduced if energy from wave power can be extracted up to its maximum. Although there are ebbs and tides, the average motion always remains. This form does not need any burning of fossil fuels for production. Remember how we discovered that wave energy is predictable? One of the best features of wave energy is that it is a renewable form of energy. Large machines have to be put near and in the water to gather energy from the waves. Now, we have an idea of the production of this energy. We’ve discussed how the wave energy machines can destroy the view of the ocean’s beauty. Marine energy has several types of energy, there are tidal energy, wave energy, ocean current energy, ocean thermal energy, and osmotic energy. They should consider the positives and negatives of this new energy source and consider who and what they may be disturbing.

Wave energy boasts many advantages such as its low cost, zero to no pollution, and a large energy output. So, we can learn that the stronger the winds are, the higher the energy transmitted to the waves is. None of this is to say that wave energy cannot be useful, but those interested in using it to create power have to look at both sides of the equation. Environmental effects. Does that mean we would not have electricity anymore? There is a need for green energy in most of our countries, this need may lead to looking for alternative renewable energy sources such as wave energy. Some forms of green power energy can function and generate power even in harsh weather conditions. Wave Energy Disadvantages. The effects of this are global warming and climatic changes. Naval Academy) clearly explains Ocean wave energy conversion in his book in Amazon. Some of the disadvantages of tidal energy are: High tidal power plant construction costs; Negative influence on marine life forms; Location limits; The variable intensity of sea waves; Although not widely used, tidal energy has the potential for future electricity generation. Disadvantage of location The downside to wave energy is the location. The energy in the wind is thus transmitted to these waves. When we install wave energy and power facilities in an underwater location, then that area becomes off-limits for any other activity. No waste products are produced. One of the most significant disadvantages of using renewable energy resources is that the primary source of generation is unpredictable. Carnegie is also working with the Mauritian Government on a CETO wave energy project and desalination plant. Huge Amounts of Energy can be Produced, 5 Practical Improvements to Reduce Your Company’s Carbon Footprint, 3. Despite its benefits, wave energy does have some negatives attached to it, namely: Stand out generators – wave energy generators can ruin the visual beauty of oceans. Several methods used to harness this energy. In a longitudinal wave, the medium movement is parallel to the wave direction. Also, we can deduce the limiting factors in the production of wave power. Image: https://gust.com/companies/bombora_wave_power. There is also a danger of toxic chemicals that are used on wave energy platforms spilling and polluting the water near them. (And Ways to Reuse Old Bottles), 13 Amazing Plants That Do Not Need Drainage Holes, Do Deer Eat Petunias? The force of the air being pushed is used to turn a turbine. Wave energy may vary due to wave speed, water density, and wavelength. Unlike ethanol, a corn product, waves are not limited by a season. It is renewable. Thus, if we only have our electricity produced from fossil fuel energy, we may suffer a huge blow when it gets depleted – and gets banned. Explaining The Ocean wave energy conversion in this article alone is not possible. The power plants harnessing the power could be put offshore. We may often confuse wave energy from tidal energy. Thus wave energy provides an inconvenience to these marine vehicles. In addition to this, the possibility of toxic chemicals from the wave energy platforms may leak or spill into the water. But, this form of wave needs a rigid medium to transmit energy. Wave energy is safe as it does not require land use. The biggest disadvantage to getting your energy from the waves is location. They require no input from man to make their power, and they can always be counted on. Some areas experience unreliable wave behavior, and it becomes unpredictable to forecast accurate wave power and, therefore, cannot be trusted as a reliable energy source. This form of energy generation is still at an infancy level. Hence, areas depending on wave power have to seek alternative methods for electricity generation. The cost of repairing, as well as acquiring such machinery, is immense. And also he provides a separate treatment of several electro-mechanical energy conversion techniques. (And 6 Clever Ways to Reuse Old Keys), Can You Recycle Shampoo Bottles? Let’s take a look. Wave energy has the potential to work with other renewable forms of energy. The waves flow back from the shore, but they always return. As its usage increases and it becomes more common, it can be expected that the costs will be normalized. Wave energy and power facilities dominate the water landscapes with their presence. The areas of greatest potential for wave energy development are in the latitudes with the highest winds (latitudes 40°–60° N and S) on the eastern shores of the world’s oceans (which border the western edges of the continents). Oceans cover the most substantial part of the earth thus making the wave energy so much available. Wave energy is also a type of renewable energy and is the largest estimated global resource form of ocean energy. These occur within the depths of the ocean. The energy production is definitely constant and viable. This may not be the case in some areas. Since the installation of these machines done in suitable sites, such sites can turn out to be passageways for cargo ships, recreational vehicles, cruise ships, and other water-body vessels. Don’t we all want electrical power production that does not affect our environment? These forms harvest the energy in the waves and easily convert it to electrical power. Thus waves will almost always crash on the shorelines of coastal regions. These drawbacks provide a reason for why wave energy may not be convenient to use despite the plenty and vast availability of water bodies. We can find out the reasons why some countries generate their power from this energy resource for commercial use. Your email address will not be published. Hence wave energy is not viable for everyone. It is a fact that the amount of energy that is produced and transported through the waves varies from season to season and from year to year. The wave energy is consistent and proves much better than other sources that are dependent on wind or sun exposure. We all know that water covers around 70% of Earth. So, they have a high potential for wave energy. We are aware that the winds generate wave energy in the oceans. Additional renewable energy resources include geothermal energy, hydrogen energy, tidal energy, wave energy, and biomass energy. Also, the lifespan of the technology used is quite uncertain in these cases. Advantages and Disadvantages of Wave Energy. Unlike fossil fuels, which are running out, in some places in the world, just as quickly as people can discover them. For … Image: http://commons.wikimedia.org/wiki/File:WD_side_princip.JPG.
